Tools needed for cutting a bridge

Recommended Posts

I'm trying to assemble a set of tools for cutting new bridges. I figure I'll need:

A knife for carving the bridge's profile.

A knife for shaping the feet.

A knife for cutting the various incisions.

Something to grind the knives into a suitable shape.

Sharpening tools.

Other tools such as a chisel for thicknessing and sandpaper for finishing.

For one of the knives I've ordered a 12mm Pfeil for carving the profile and cutting the feet, but I'm going to need a smaller knife for shaping the heart, kidneys, ears, and other such parts of the bridge. Would a smaller Pfeil knife be good for this? What size?

Once I have the right knives the next step is to give them the desired shape. For the shapes of the knives, Johnson & Courtnall recommends giving the blade a knee for cutting the bridge profile and feet, but for the other cuts it says only to use a fine blade. What would be the best shape for this blade?

Also, what's a good tool for altering the shape of the knife as opposed to just sharpening?

I can only share what I use, but I also know not everyone does the same. It's a combined result of how I was taught + the tools I happen to own because I like them & could acquire them on my budget at the time.

Block plane for initial thickness (I could probably use the chisel instead if I was trying to go really minimalist/budget)

The triangle strings website has excellent information. You don’t need a lot of tools to do it, but it’s worth investing in good ones if you intend to cut a lot of bridges.

There are all kinds of opinions about what kind of grinder/honing setup you ought to have, but it will ultimately come down to what works most consistently and efficiently for you. Get a good block plane and a couple knives that have good quality steel that will hold an edge. I use a bench chisel for initial fitting and thicknessing, but that’s my personal preference, not a necessity (I think it saves me a little time and keeps my plane blade sharp longer). These are the basics, below I’ll list some other tools to consider.
